Question

Effect of a tax on buyers and sellers

The following graph shows the daily market for shoes when the tax on sellers set at $0 per pair.

Suppose the government institutes a tax of $23.20 per pair, to be paid by the seller. (Hint: To see the impact of the tax, enter the value of the tax in the Tax on Sellers field and move the green line to the after-tax equilibrium by adjusting the value in the Quantity field. Then enter zero in the Tax on Sellers field. You should see a tax wedge between the price buyers pay and the price sellers receive.)

Use the graph input tool to help you answer the following questions.

Fill in the following table with the quantity sold, the price buyers pay, and the price sellers receive before and after the tax.

Using the data you entered in the previous table, calculate the tax burden that falls on buyers and sellers, respectively, and calculate the price elasticity of demand and supply over the relevant ranges using the midpoint method. Enter your results in the following table.

The burden of the tax falls more heavily on the ______ (less or more) elastic side of the market.

Explanation / Answer

Here first you need to estimate the demand and supply function to analyse tax behaviour. Take the following values of demand and supply fro, the graph and find the relevent demand and supply equations.

Note that these values are taken from the graphical demand and supply equations. At first, use only first three columns and note the equation they form using excel trendline or by mannualy finding them. The demand and supply euqations are:

Pd = 350 - Q and Ps = 60 + 0.16Q, Equate them to find the equilibrium price before tax

350 - Q = 60 - 0.16Q

290 = 1.16Q

Q = 250, P = 350 - 250 = $100

After the tax is imposed on sellers. the equation of supply changes to Ps = 60 + 0.16Q + 23.20 or Ps = 83.20 + 0.16Q. The new after tax price and quantity are:

350 - Q = 83.20 - 0.16Q

266.8 = 1.16Q

Q = 230, P = 350 - 230 = $120

This is the price paid by the buyers. Price received by the sellers is Ps = 60 + 0.16*230 = 96.8

Hence, we have te table as:

Quantity

Price Buyers Pay

Price Sellers Receive

(Pairs of shoes)

(Dollars per pair)

(Dollars per pair)

Before Tax

250

100

100

After Tax

230

120

96.8

Price elasticity using mid-point method is:

            = (Q2Q1) / [(Q2 + Q1)/2] / (P2P1) / [(P2 + P1)/2]

Price elasticity of demand ed = (230 - 250) / [(230 + 250)/2] / (120 - 100) / [(120 + 100)/2] = 8.33%/18.18% = 0.48

Price elasticity of supply es = (230 - 250) / [(230 + 250)/2] / (96.8 - 100) / [(100 + 96.8)/2] = 8.33%/3.25% = 2.56

The results are as follows:

Tax Burden

(Dollars per pair)

Buyers

0.48

Sellers

3.2

2.56

This suggests that the burden of tax falls more heavily on the less elastic side of market
